END BAR FOR BED-SPRINGS.

To all whom t may concern Be it known that I, CHARLES EHRLICH, a citizen of the United States, and a resident of'New York city, borough of Brooklyn, in

the county of Kings and State of New York, A

have invented certain new and useful Improvements 1nv End Bars for Bed-Springs, of which the following is a specification.

This invention relates to bed springs, par-V tages will more fully appear hereinafter and will be particularlypointed out in thev claims. Y l

In the drawings illustratingV this invention, Figure 1 is a plan view of the improved end bar showing a fragmentof the spring extending thereover. Fig. 2 is a plan of the improved end bar showing the sections of the same open during the process of as sembling the device. Figs. 3 and 4 are plan views illustrating fragments of the sections comprising the improved end bars. Figs. 5 and G are respectively sections taken along line 5-,5 and 6-6 of Figs. 3 and 4. Fig. 7 is a detail view illustrating the section correspending to Fig. 3, with the Vteeth flat previouslto bending over. Fig. 8 is'a cross sectional view illustrating the position of parts during the process of assembly. Fig. 9 isa fragmental plan view illustrating a modified form of bar. Fig. 10 is a cross sectional view of the form in Fig. 9,`illustrating the parts during the process of assembly.

Referring in detail toFigs. 1 to 8, the end bar consists of two sections 10 and 11 provided with intermeshing portions which grip the end of the spring 12,and clamp the individual strand securely in place. These intermeshing portions consist of a plurality of teeth 13 formed along one edge of the section 10 and corresponding perforations 14 formed along the adjacent edge of the section 11. Vhen the parts are assembled, the

end of the spring 12 is placed over the up- Vturned teeth 13 of the section 10 and the section 11 is then placed over the teeth which Y pass through the perforations 14. A. rod 15 may then be placed along the marginal edge of the section 11 adjacent to the teeth 13 as clearly illustrated in Figs. 2 and 8, and the teeth may then be bent over the rod by some suitable means into the position illustrated in full lines in Figs. 2 and 8. lf desired, these teeth may be bent over simultaneously with thesection 11 as the latter is swung over into the position shown in dotted lines in Fig. S. The teeth 13 are thus bent about the wire and securelyv held thereto by the section 11 which is bent thereover. To completely inclose the end of the spring held by the endbar, the section 11 may be formed with extended portions or flaps 16 and 17 respectively on the longitudinal and end edges of the section 11. These extensions or `aps are turned over the edges of the section 10 as illustrated in dotted lines in Fig. 1, and'thus securely hold the two sections together, as well as form a tight, dust-proof casingv for the end ,of the spring. Preferably the sections of the end bar are formed of sheet metal stampings which may be formed entirely in one stamping operationl in which the outline of the sections are formed as well as the teeth or perforations, as the case may be. Preferably, additional perforations may be formed in the sections during the stamping operation, which perforations may be utilized as points of attachment of the end bar to the frame of the spring. Thus, perforation 18 may be formed in the section 10 and perforation 19formed in the section 11, so disposed as to register over another when the bar is assembled, as

ln the modified form illustrated in Figs. 9 and 10, the rod 15 is omitted and the teeth 13 of the section 10a are bent over the adjacent edge of the section 11a. If de? sired, the flaps 16a and 17ZL may be formedV upon the section 10 containing the teeth instead of the section containing the perforations as in the other form illustrated.

1t will thus be seen that I have provided l an end bar for bed springs which snugly Patented Nov. 2, 1915.

or the disengagement of the strands of the Yspring is rendered impossible forl all practical purposes. It will be also clear that by reason 'of the disposition ofthe teeth which are turned in the direction of the wires of 'the,spring, they may assist further in holding the spring from disengagement from the end bar. Thus, as clearly appears from Figs. 9 and 10, if the teeth are made long enough, their points may directly engage jthe Wires and thus tend to further assist in holding the spring' in position: The teeth in allmcases entirely fill the perforations when the parts are bent in place and thus renderv the; casing dust-proof at those points. The marginal kflaps inclose the other edges of the casing and thus complete the dust-proof l' inclosure.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. An end bar for bed springs comprising .i two sections having intermeshing portions,

one series of said 'intermeshing portions passingfthrough the strands of the spring, the opposing Vsection being bent over the iirst section and inclosing said series of intermeshing portions and holding them from disengagement.

, 2.V An end bar for bed springs comprising vtwo .sections havingl intermeshing portions, one series of said intermeshing portions passing through the strands of the spring,

arod adjacent thereto, the opposing section' being bent over said series of intermeshing v vportions inclosing the latter and holding i them against the rod.

'l 3. An end bar for bed springs comprising two sections, one'of which is provided with 'teeth and the other of which is formed with apertures, said teeth being adapted to pass throughthe mesh of the spring and then through the apertures 'of the opposing section, a rod adjacent to the teeth, said opposing section bemg bent over to inclose the teeth and hold thesame securely against the rod.

5. An end bar for bed springs comprising Vtwo sections, one of which is formed with Vof which has a series of marginal perforations and the other having a series of marginal teeth passing through the perforations and turning in the direction of the free ends of the strands of the spring, said teeth being held by the body of the opposing bar section toward the spring and concealed thereby, and flaps on one of the sections engaging the other section for inclosing the end of the spring.

7. In combination with a wire bed spring, of an end bar comprising two sections, one of which has a series of marginal perforations and the other having a series of marginal teeth passing through the perforations and turning in the direction of the strands of the spring, said perforated section being bent upon the body of the opposing bar section to inclose the teeth and the spring end, and iiaps on one of the sections engaging the other section for binding the two sections together, the teeth substantially entirely lling the recesses when the sections are bent into position to clamp the end of the spring.

S. In combination with a bed spring, of an end bar therefor comprising two sections, one of which is formed with marginal perforations and the other with marginal teeth passing through the periolations and disposed between the two sections and inclosed thereby, the teeth filling the recesses to prevent access offoreign matter into the casing formed by the end bar, and flaps for engaging the free marginal edges of the sections along their entire length to completely inclose the end of the spring and to form a dust-proof casing therefor.

Signed at New York city, in the county of New York, and State of New York, this 5th day of December, A. D. 1913.
